We build blockchain products for companies in Paraguay with our in-house team, and we design each token knowing whether it is a virtual asset or one of the distributed-ledger securities recognized by Law 7572/2025.
Tell us about your project
We turn your use case into a product you can launch, operate and grow. The same team designs the architecture, writes the contracts and integrates them with your systems.
Tell us what you want to buildParaguay keeps three regimes apart: registration with SEPRELAD, reporting to the DNIT and securities law. Before choosing a network we decide where each function falls, because that changes the supervisor and the data the platform must keep.
We write your business logic with tests and peer review. The code is prepared for an external audit and a phased deployment before it runs in production.
You speak Spanish directly with the people who design and code. Meetings fit into your office hours, and between them the project carries on through shared documentation and a stable technical channel.
We document the code and plan deployments and monitoring. Your team receives a technical foundation for maintaining the product and adding features.
We cover the full Web3 product lifecycle, from idea and MVP to mainnet, audits and maintenance.
Scope not defined yet? Start with blockchain consulting
From cattle ear tags to maquila programs, these cases start from controls Paraguay already applies and from a securities law that accepts distributed ledgers.
Bonds of an agribusiness issued and recorded on DLT, a way of representing securities that Article 73 of Law 7572/2025 expressly includes.
Blockchain for Banking & Finance
In SITRAP, regulated by SENACSA, each animal carries its ear tag, and its origin and movements are recorded up to slaughter; the on-chain layer mirrors them without replacing that system.
Blockchain for Agribusiness
Law 6676/2020 bans the trade in charcoal from unpermitted forest clearing in the Eastern Region for ten years; every batch linked to its plot and its permit.
Blockchain for Energy & Sustainability
Maquila accounted for 68% of Paraguay's exports of industrial manufactures in 2023; every temporarily imported input traced to its re-export under Law 1064/1997.
Blockchain for Supply Chain & LogisticsOur stack covers every layer of your product: smart contracts, blockchain networks and integration with your systems. We use it to build, test and deploy software tailored to your business.
The smart contract language for verifiable rules on EVM networks.
Performance and memory safety for contracts, nodes and Web3 tooling.
EVM contracts, tokens and final settlement on an open Proof of Stake network.
An environment to compile, test and deploy contracts on EVM networks from Node.
Solidity tests, invariant fuzzing and command-line tooling for EVM networks.
Oracles for external data, randomness and cross-chain messaging for contracts.
Polygon PoS: EVM contracts secured by its own validators, with low fees.
Programs, accounts and parallel execution on a high-throughput layer 1.
Audited Solidity contracts for tokens, access control and upgradeable systems.
Paraguay splits the framework into three regimes that do not replace one another. Virtual asset service providers register with SEPRELAD for anti-money laundering purposes; Law 7572/2025, applied by the Central Bank through its Securities Superintendency, covers securities issued and recorded on DLT; and DNIT Resolution 47/2026 adds an information return on crypto-assets. No registration or return amounts to a financial license.

Every delivery goes through the same checklist before it reaches mainnet. What changes between projects is the depth of each control, because an MVP does not carry the same risk as a contract that holds third-party funds.
What we are asked before a project starts.
Talk to our teamIt depends on each function. Anyone providing exchange, transfer, custody or management services for virtual assets registers with SEPRELAD and applies its AML controls; if the token grants negotiable credit, ownership or participation rights, it falls under Securities Market Law 7572/2025; and the DNIT sets an information return for the persons covered. None of those steps is a financial license. We analyze the fit of your case before writing any code.
Yes. We support startups from MVP validation to their first round, and established companies on tokenization, traceability and digital identity projects with strict compliance requirements. In every case, smart contracts go through tests and review before they reach mainnet.
In Spanish, talking directly to the people who design and build the product. Meetings are fitted to your working day, and the rest moves forward through shared documentation, written decisions and a stable technical channel.
It depends on product complexity, integrations and the level of review it needs. Before development we set scope, dependencies and phase deliverables. That lets you decide what reaches production first and what waits for a second iteration, without mistaking an MVP for the complete architecture.
The one the product requirements call for, not the trend of the moment. For EVM projects we compare Ethereum, Polygon, Arbitrum or Base on finality, costs, tooling, interoperability, custody and compliance, and we consider non-EVM networks when they fit better. The recommendation covers contracts, indexing, wallets and operations, with the product's users in mind.
Tell us about your case and we'll propose architecture, timeline and budget within a week.
We work remotely with teams throughout the country, and on site where the project calls for it.
